Usage instructions

Getting a ready release

1. Go to the releases tab
2. Get the latest release depending on your system

Compiling it yourself (will run faster)

1. Ensure you have git, make and a C++ compiler installed
2. Clone the repository with submodules:

git clone --recursive https://github.com/ilya246/atmosim
cd atmosim

3. Build using the Makefile:

make -j

Using AUR (on Arch Linux)

yay -S atmosim

This also installs configs into /etc/atmosim/

Running

1. Open a console (on Windows press win+r then type in cmd), then cd .../path/to/atmosim, path/to/atmosim being its location on your disk
2. Run atmosim -h or atmosim.exe -h
3. Refer to the help readout for further usage instructions

zsh

Zsh (default on MacOS) treats [] as pattern matching. And since atmosim takes many arguments in [], you would need to overwrite this behaviour by wrapping [] with "": -mg="[plasma,tritium]"

Configuring constants

(nearly) all the constants can be configured in a toml file, in case if they are different on a fork. By default, atmosim reads the configuration.toml file from the current working directory. You can overwrite this with ATMOSIM_CONFIG enviroment variable. In cmd on Windows:

set ATMOSIM_CONFIG=configs/monolith.toml
out/atmosim.exe

Bash: ATMOSIM_CONFIG=$HOME/.config/atmosim/my_fork.toml ./atmosim. Here are the options:
